The red curve is the graph for given function.
Step-by-step explanation:
We are given the following function in the question:
We have to graph this function.
Properties of function:
- The given function is an exponential function of the form , where b is the base and x can be any real number.
- Here,
- It passes through the point (0,1).
- Since , the graph of function will decrease as we move from left to right.
- The domain for given function is all real numbers.
- The range for the given function is
The attached image shows the graph for the given function.
Answer:
<em>Javier deposited $178.79 initially</em>
Step-by-step explanation:
<u>Compound Interest
</u>
It occurs when the interest is reinvested rather than paying it out. It's basically earning interest over interest.
The formula is:
Where:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
If the final amount is known, we can solve for the principal:
Javier opened a savings account t=5 years ago. The account has an interest rate of r=3%= 0.03 compounded quarterly. Since there are 4 quarters in a year, n=4. The current balance is A=$200. Let's calculate the initial balance or principal:
Javier deposited $178.79 initially
Answer:
1000 miles
Step-by-step explanation:
Divide how long Jack's family traveled before he fell asleep by the percent of the trip.
430/43% = 1000
The trip was 1000 miles
You can check this by multiplying the total miles of the trip by the percent
1000 x 43% = 430
Amount financed
320-20=300
Total paid
34×10=340
Interest
340-300=40
Interest rate
((2×12×40)÷(300×11))×100
=29.09%
Hope it helps
